Disclosed is a composition for softening an absorbent tissue and tissue structures softened using the composition. The composition includes an effective amount of a softening active ingredient; a vehicle in which the softening active ingredient is dispersed; an electrolyte dissolved in the vehicle; and a bilayer disrupter. The electrolyte and the bilayer disrupter cooperate to cause the viscosity of the composition to be less than the viscosity of a dispersion of the softening active ingredient in the vehicle alone. Preferably, the softening active ingredient is a quartenary ammonium compound with the formula I: (R1)4-m - N+ -[(CH2)n - Y - R3]m X-; the vehicle is water, the electrolyte is calcium chloride, and the bilayer disrupter is a nonionic surfactant.

L'invention concerne une composition permettant d'adoucir un papier de soie absorbant et d'autres structures en papier de soie. Cette composition comprend une quantité efficace de principe actif adoucissant; un vecteur de dispersion de ce principe actif; un électrolyte dissous dans le vecteur; et un dislocateur de bicouche. L'électrolyte et le dislocateur de bicouche coopèrent pour réduire la viscosité de la composition par rapport celle d'une dispersion du même principe actif dans le vecteur seul. De préférence, le principe actif est un composé à base d'ammonium quaternaire représenté par la formule: (R1)4-m - N<+> - [(CH2)n - Y - R3]m X<->; le vecteur est de l'eau, l'électrolyte est du chlorure de calcium, et le dislocateur de bicouche est un tensioactif non ionique.
